HOT-WATER yALvE.

SPECIFICATION forming part of Letters Patent No. 510,420, dated. December 12, 1893.

Application led October 4, 1892.. Serial No. 4471328 (N0 mvdL) To all whom it may concern:

Be it known that I, FRANK C. GOFF, a citizen of the United States, residing at Denver,

in the county of Arapahoe and State of Colorado, have invented a certain new and `useful Improvement in Hot-Water Valves, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a vertical central view of my valve as applied to a hot waterradiator. Fig. 2, is a transverse, sectional view, taken at the l1ne 2-2, Fig. 1. Fig. 3, is a sectional view, taken at the line 3 3, Fig. 1, looking to the right, not showing the radiator. Fig. 4, is a detached view of the valve.

The object of my invention is to make a hot Water valve which controls or regulates the flow and return of the water, thus enabling me to make only one connection to the radiator.

My invention consists of the mechanisms and combination of mechanisms hereinafter fully described and made the subject matter of the claims.

In the accompanying drawings, A, represents a hot water radiator. B, is the wall of the room in which it is placed.

C, is a pipe leading froln the bolerorheater in which the hot water fiows to the radiator.

D, is the return-pipe in which the water returns to the boiler.

E, is a two-way coupler to which the pipes C and D are joined, said coupler having two openings at one end and one at the other, and having a partition,F, which prevents the openings which lead into the pipes O and D from communicating with each otherin the coupler.

G, is a two-way pipe, having a partition, H, which preventsv the tWo Ways in the pipe from communicating with each other. v

I, is a two-way valve-case, having a partition, J, extending through the length of its opening, excepting the space occupied by the valve. v

K, is the valve proper, having two openings, L and M, each of them leading from the end and passing out at the side of the valve. This valve is held in its seat in the valve-case by the hollow screw-plug, N, which screws into 5o the valve-case, I, and also forms a seat for the valve-stem, O.

O is a partition in the Valve.

P, is a packing-box for the valve stem O. The two-Way screw-plug Q is screwed into the radiator A, and the valve-case I is secured to it by means of the screw-cap, R. One part of the screw-plug Q is longer than the other side, as shown at S, so that the warm water coming from the boiler is admitted into the radiator above the opening for the return water to pass back to the boiler.

U, is a small screw closing and opening into the return passage in the two-way valve, which can be removed to drain the radiator, if desired.

The valve K shown in Fig. 1, is turned so that the openings in it register with the openings in the valve-case and the two-Way pipe S, so that the flow of water to the radiator is uninterrupted and the return is also uninterrupted by turning the valve K one-half around, so that its openings are thrown into the position shown in dotted lines in Fig. 1. Both openings through the pipes and valve are closed, so that, by turning the valve K, the hot water is shut off from passing through the radiator, and the Water is also prevented from flowing from the radiator. I have shown the partition between the openings in the end of the valve K, as well as in the valve-case at T, slightly staggered, so that when the valve is closed, as shown by dotted lines in Fig. 1, there is an opening from one passage in the valve-case into the other passage, giving a continual slight circulation of the Water through the pipes to prevent freezing.

By this construction of my valve and connecting pipes, I have a single connection for the Water to flow to the radiator and return. This arrangement gives me great facility in placing the liow and return-pipes in the same recess in the wall leading from the boiler, which is usuallyin the basement, through the radiators throughout the building, and when they reach the radiator it is only necessary in order to make connections to have one hole through the floor or board' of the partition, and one opening into the radiator. I am able to make connections throughout a building from the boiler to the radiators with great fa-` cility and with little expense.

What I claim, and desire to secure by Letters Patent, is=

l. A valve-case having within it a seat for IOO Vmog-teo a plug-valve, and two openings adapted to connect two pipes to the valve-case, and an interior partition extending from the valveseat to the openings adapted to receive a connecting pipe, thus providing two ports from the valve-seat in each direction to the connecting pipes; a plug-valve tted within the valve seat and having two ports extending through it, the division between the ports being made to connect with the partitions leading from the valve-seat to the pipe openings in the valve-case when the plug valve is turned into a certain position and to close the openings leading into and out of the valve-.case when turned in certain other positions in the valve-seat, whereby I have two passages through the valve and only two pipe connections to the valve, as specified.

2. The two-way hot water valve; the twoway screw-plug; a radiator with a single opening which receives the two-way screw-plug, the two ways of the screw-plug registering with the two-ways in the case of the valve, whereby the wateris admitted and discharged from the radiator through one opening in the radiator and through one valve, the valve closing the two ways in the valve-case simultaiieously.

3. A two-way valve-case having a two-way plug-valve; a two-way connecting pipe con,-

nected to one end of the valve-case; a threepipe coupler to couple the hotwater pipe and the return-pipe tothe two-way connectingpipe; and the het water pipe and return-pipe, whereby I am enabled to supply hotwater to a radiator by running a single pipe in the room connecting with the two-way valve which controls the inlet and outlet of hot water to and from the radiator, as specified.

4. The valve-case having a valve-seat; and two openings in the valve-seat divided by a partition from the valve-seat to the pipe connections for each opening; a plug-valve having two openings through it, the division between the openings at one end staggered relative to the division between the opening in the valve-case, whereby the two ports in the opening into the valve-case register with the ports in the valve when the Valve is open, but admit the openings on each side of the `division in the valve-case to communicate with each other when the valve is closed through which the water passes directly from one part of the opening in the valve-case to the other part of the opening, as specified.
